Transmitter Withstands Harsh Conditions

The AST46HA Series are explosion-proof transmitters with pressure ranges up to 20,000 psi and new certifications to withstand harsh conditions found in offshore, marine, deep well drilling, oil processing, and mining applications. The products are constructed of thick diaphragms and silicon strain gages. A fail mode indicator option lets you choose an output signal that rails or drops during a fault condition, providing better control on how your systems react should sensors fail. If the transmitter fails while running a system, the output signal can go 5% above the maximum or 5% below the minimum to indicate a transmitter problem. Vented and non-vented versions are available along with F250C female process ports for robust high-pressure process connections.
